Abstract
This application provides a security authentication method and apparatus applied to Wi-Fi, to help prevent a password from being shared among a plurality of devices, and implement management of a second device by a first device. In the method, an access point AP receives a first password input by the first device, where the first password is a password preset before delivery; and when checking the first password by the AP succeeds, the AP obtains a second password shared between the AP and the first device, and performs a 4-way handshake with the first device based on the second password. The second password is a shared key between the first device and the AP. Then, the AP can receive a first request from the first device, and send a third password to the first device in response to the first request.
